I'm looking at the Asus Nforce 4 SLI Ultra board too and the 3500.

I see 2 versions of it.

The Newcastle one and the WInchester one. The Newcastle is 1.3 and Winchester is .90 I heard the .90 is alot better, but its about 60 bucks more. That 60 bucks could be used to buy an extra 512mb of 3200 ram.

The .90 might be alot cheaper when I buy ( summer or maybe end of year ) But I guarentee I will be buying sometime this year.

Thanks.
